HAS Hollywood forgiven Mel Gibson for his drunken anti-Semitic rant two years ago? One source said, “He’s a pariah in Hollywood,” adding that studios have refused to distribute Gibson’s next movie, “Edge of Darkness.” But independent producer Graham King told us, “The only reason I didn’t sell the movie [to a studio] is I had to get a SAG waiver. If I had a distribution deal with a studio, I never would have gotten the waiver.” The Screen Actors Guild is expected to go on strike June 30, and shooting for “Edge of Darkness” is slated to start Aug. 18. Asked if there was a boycott against Gibson, King, who won an Oscar for “The Departed,” said, “I don’t think so. We took the movie to Cannes. I sold the movie in Israel. It surprised the hell out of me.” William Morris agency chairman Jim Wiatt said, “It’s not true that the studios won’t work with Mel. He’s been offered movies by Fox and Warner Bros. and others.”
